Abstract: A method and an apparatus for optical inspection of transparent articles. The method and apparatus use a light beam scanning field which is separated into at least two portions. The field portions are directed at the article at differing angles of incidence such that they eliminate blind spots caused by portions of the apparatus which block the passage of the light through the article. A feature of the invention is its provision of a folded optical path to increase the length the beam travels between the beam generator and the object beyond the physical distance between the beam generator and the object.

Granted: 1989-05-17
Abstract: A device for dispensing a liquid from a collapsible container comprises a pair of elastic plates (2,4) hingedly mounted to each other along one edge (6) permitting them to be pivoted to an open position or to a closed position, and a sleeve (8) of flexible material secured to the pair of elastic plates (2,4) along their hinged edges for receiving a liquid-filled collapsible container (10). Each of the elastic plates (2,4) is preformed with a curve which is convex from the side facing the flexible sleeve (8). The arrangement is such that when the liquid-filled collapsible container (10) is received within the flexible sleeve (8) and the two curved elastic plates (2,4) are pivoted to their closed positions, they apply, due to their elasticity, a continuous force to the collapsible container (10) for dispensing the liquid therefrom. The device further includes retainer means (14,16,18, 20,22,24) for releasably retaining the elastic plates (2,4) in their closed position.

Title: Card clothing grinding
IPC: B24B19/18
Filed: 1988-12-14
Granted: 1991-10-16
Abstract: The card clothing elements (17) of a carding machine are ground using an abrasive material which is resiliently pretensioned against the card clothing teeth. It is customary in the field of spinning to grind the card clothing teeth from time to time in order to resharpen them when necessary. This has the disadvantage that for this purpose the carding machine needs to be taken out of service for certain time intervals. Moreover, the wear at the tips of the teeth is responsible for a gradual, continuous deterioration in web quality, which suddenly improves on grinding. The last-mentioned factor makes it difficult to produce yarns of uniform quality. 
<??>These disadvantages are to be avoided by subjecting at least one card clothing element (17) of the carding machine to grinding while in service in a grinding process brought about by the in-service movement of the card clothing element (17) and by making the grinding area (31) of the process material (22) movable in three degrees of freedom in a resiliently pre-tensioned position. An additional benefit is uniform wear of the teeth.
